Basic Question About Complex Impedance Numbers
Hello all...
I have a dipole that I ran a sweep on with NanoVNA Saver, and a NanoVNA-H. When looking at the complex impedance at the closest point to resonance ('0' reactance), I get numbers like 56.3-j697m ohms (no 'ohm' symbol on my laptop). What does the 'm' mean? I'm assuming that means the reactance part is very close to '0'. Is that correct, or am I all wrong? Thank you for your time. |

Hello all...milli. so it's 0.697 ohms. |

I believe the m stands for milli (1/1000).

Lower case indicates "milli" or 1E-3. So, your reading of -j667m means

-j667 milliohms or -j0.667 ohms. This is known as scientific notation or, more specifically, engineering notation, engineering being powers of 10 modulo 3. Also note that M indicated "mega or 1E+6. On Tue, Oct 6, 2020 at 11:28 AM <ed.jackson001@...> wrote:
